885128

2.4 GHz RF BAW Filter - Long-Term Evolution Coexistence

Qorvo's 885128 is a high-performance, high power Bulk Acoustic Wave (BAW) band-pass filter with extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi band and high band-edge & near-in rejection.

The 885128 enables coexistence of Wi-Fi andLong-Term Evolution signals within the same device or in close proximity to one another. Its unique power handling capability allows for implantation into access points and small cell base stations.

The 885128 uses common module packaging techniques to achieve the industry leading small size 1.1 x 0.9 x 0.5 mm footprint. The filter exhibits excellent power handling capabilities.
